Recent strength in NVIDIA shares, trading near $234 after hitting an intraday record of $237.88 on October 2, stems primarily from the company's $150 billion share buyback expansion and sustained AI infrastructure demand, including Blackwell ramp and agentic AI tailwinds. Data center revenue exceeded $89 billion in the latest quarter with $108 billion Q3 guidance, yet supply constraints and macro factors like Fed policy expectations introduce volatility. With next earnings slated for November 18, the closely matched Polymarket probabilities around the $230–$240 range capture trader consensus on near-term momentum balanced against potential swings from economic data or sector rotation.
